The BPC includes a housing. A cavity is disposed in the housing, and the cavity is filled with a dielectric. A light entrance that presents a concave spherical surface and that is recessed towards the cavity is disposed on a side of the housing, a light exit is disposed on a side of the housing that is opposite to the light entrance, and a side of the light exit that is away from the cavity is configured with dielectric multilayers that has a filtering function. Compared with a conventional CPC, the BPC implement the larger field of view, higher optical gain, reduced mass, and filtering function. The VLC system using the as-proposed BPC clearly increase the communications distance, bandwidth, and receiving field of view, and reduce the overall complexity and costs."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Band-pass concentrator for visible light communications system and visible light communications system","description":"This application discloses a band-pass concentrator (BPC) for visible light communications (VLC) and a VLC system.
